About Manufacturer

Supersprint: Elevating Automotive Performance Since 1955

At Supersprint, their journey began in 1955 with a steadfast commitment to excellence in crafting high-performance exhaust components. Over the decades, they have remained unwavering in their pursuit of perfection, setting new standards in the world of automotive enhancement. Their core values revolve around the relentless pursuit of quality, precision, and innovation, all culminating in an unrivaled product lineup. We, MADNESS Autoworks, are proud to be an Authorized Partner for Supersprint in North America, offering you access to their exceptional range of products.

**Craftsmanship Beyond Compare**

Supersprint's dedication to excellence starts with their materials, where they exclusively utilize the highest-grade stainless steel, predominantly AISI 304. In demanding situations requiring exceptional resilience, such as turbo manifolds, they turn to AISI 310S and Inconel. Every detail, from attachment hardware to weld quality and component joints, undergoes meticulous scrutiny to ensure uncompromising quality and durability.

**Custom-Engineered Excellence**

Supersprint takes pride in treating each new vehicle exhaust application as a bespoke endeavor. They shun the one-size-fits-all approach, opting for tailored solutions that optimize performance and refine sound characteristics. By designing each component with precision and finesse, they ensure consistent performance gains across the entire rev range, while maintaining a harmonious and sporty tone.

**The Pinnacle of Design and Innovation**

Their process begins with thorough research and development, driven by their passion for automotive excellence. The journey takes them to their state-of-the-art R&D facility in Mantova, where they scrutinize every facet of a vehicle's performance. Using their MAHA AWD dynamometer, one of the most accurate in the industry, they collect baseline measurements, including horsepower and torque, to set the stage for enhancement.

**In-House Mastery**

Supersprint components are born in their facility, guided by cutting-edge CAD software and crafted by the skilled hands of their technicians. Piping thickness is meticulously maintained at 1.5mm, and all piping undergoes mandrel bending to optimize performance. Connections between sections are expertly TIG or MIG welded for unparalleled strength and sealing.

**Sound and Performance in Perfect Harmony**

While performance is paramount, they are equally dedicated to preserving the sporty character of your vehicle's exhaust note. Their mufflers, produced in-house, shed weight through reduced thickness piping and sheeting. The "direct flow" design minimizes back pressure across the exhaust system, ensuring optimal engine performance.

**Aesthetic Excellence**

They understand the importance of aesthetics in automotive enhancement. Supersprint exhaust systems not only perform flawlessly but also enhance the visual appeal of your vehicle. Their exhaust tips, available in over 30 designs, all proudly bear the Supersprint logo inscribed with a micro-percussion system.

**Setting Global Standards**

Their commitment to quality extends beyond borders. Supersprint components meet or exceed the stringent European TUV requirements. Certain combinations of rear mufflers and center resonators are CEE homologated, ensuring compliance with European sound level standards.

**A World of Performance**

With a presence in over 80% of global markets, Supersprint's reputation spans the globe. Renowned tuning firms, especially in Germany, trust their expertise to create private-label exhaust systems for a wide range of vehicles, from premium luxury models to high-performance exotics.

**Your Choice for Excellence**

Choosing a Supersprint exhaust system is choosing the pinnacle of automotive performance and craftsmanship. Whether you drive a sporty city sedan or a dream supercar, Supersprint delivers the perfect fusion of power and sophistication. Elevate your driving experience with Supersprint, where every journey is a symphony of performance and class.
